Expect, a core component of the Jest testing framework, has released version 29.4.2, building upon the previous stable version 29.4.1. Both versions essentially provide the same core functionality: exporting the expect function, a crucial tool for writing assertions in JavaScript tests, primarily used within the Jest ecosystem. Developers familiar with Jest will find no functional difference in the core API exposed by expect between these two releases. The main difference lies in the updated dependency versions. In the newer version 29.4.2, several dependencies have been bumped including, jest-util, jest-get-type, jest-message-util, @jest/expect-utils, and jest-matcher-utils reflecting internal updates and improvements within the Jest project. Notably in v29.4.1, 'jest-get-type' was on v29.2.0 and is now v29.4.2 in v29.4.2. From a developer's perspective, these changes are typically transparent, focusing on internal refinements and bug fixes within Jest rather than introducing breaking changes to the expect API. Depending on the lock file or package manager v29.4.2 could result in a lighter package than 29.4.1, as indicated by the unpackedSize attribute (144731 vs 270595 bytes). Version 29.4.2 was released on February 7, 2023, while version 29.4.1 came out on January 26, 2023, so developers are encouraged to update to the newest version (29.4.2) to benefit from the latest improvements.
